PRESSURE DEVICE FOR BURNERS.

SPECIFICATION forming part of Letters Patent, No. 639,197, dated December 12, 1899.

Application filed October 23, 1899. Serial No. 734.576. (No model.)

To all whom t may] concern:

Be it known that I, GUsTAvE A. LonBnN, a subject of the Emperor of Germany, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Pressure Devices for Burners, ot' which the following is a specification.

The object of my invention is to automatically regulate the pressure in an apparatus for supplying fluid to a burner or a series of burners.

My invention is especially applicable to burners using hydrocarbons or other fluids capable of being gasied.

In the accompanying drawings, Figure lis a view of a lamp, partly in section, illustrating my invention. Fig. 2 is a view showing my invention as applied to a central supplytank connected to a number of pipes, and Fig. 3 is a view of a diaphragm-regulator.

Referringin the rst instance to Fig. l, A is the reservoir, from which extends a pipe a, connected to the inlet b2 of a regulator B. This regulator in the present instance is of the float type, having a valve b attached to a lever h', coupled to a float b3, and above the iioat is an air-chamber forming a cushion. The valve can be adjusted on removing a plug in the bottom of the inlet b2. The valve can be turned, as it is in the form of a screw. b4 is the outlet, which is connected to a tube d, having a valve d'. This tube d is connected by a branch cl2 with the burner D. This burner in the present instance is so constructed that the liquid in passing through the burner to the outlet will be vaporized or gasied. The burner has a suitable valve cl3 for regulating the flow of vapor or gas. Above the burner in the present instance is an incandescent mantle c, carried by a support c of the ordinary type. Coupled to the pipe CZ isa tube c, extending to the expander E. This expander in the present instance is simply a continuation of the tube e and is coiled in any suitable forni directly abovethe mantlc and within the heat zone of the same. The tube is extended in the form of a branch c and is attached to the upper portion of the reservoir A. c2 is a valve to regulate the flow of the liquid through the tube c. In this view I have shown a gage F, although this can be dispensed with in most instances. f is a capped opening through which the reservoir can be charged with liquid.

In operating the lamp shown in Fig. 1 the reservoir is charged with any suitable ignitible fluid, such as any of the ordinary hydrocarbons, and the section of tubing between the valves d', d3, and e2 is heated in any suitable manner--by a torch, for instance-the valve ol/ being closed and the valves Fand e2 opened. The liquid in this portion of the tube will be heated and in time vaporized or gasified, and the gas escaping from the burner can be then ignited, heating the mantle to incandeseence, and the liquid iiowing into the expander will be at once vaporized or gasiied and pressure will be developed in the upper portion of the reservoir. The valve cl' is opened after the section ot tubing is heated, so that the'iluid under pressure will flow to the burner and to the expander.

In some cases the air in the expander may be heated at first, so that the expanded air will create a certain pressure on the liquid in the reservoir prior to the gasifying of the liquid passing to the pipe c. As the pressurein the reservoir increases the air in the regulator will be compressed and the float will be raised and will reduce the passage leading from the reservoir to the burner and expander, and when the pressure reaches the point at which the regulator is set the flow of liquid Will be entirely cut ot't'. As soon as the pressure is reduced the valve will open, allowing the liquid to ovv through the regulator Vand into the pipe d and to the burner and gasitier. In time the regulator will be set, so that a constant pressure is maintained in the reservoir.

In Fig. 2 I have shown anl apparatus soulewhat similar to that shown in Fig. 1, with the exception that the construction illustrated in Fig. 2 is intended for a central reservoir for use at a central point, from which a line of pipe coupled to any number ot' burners may be attached-such, for instance, as in a building using one reservoir for a number of hydrocarbon-burners. In this construction a special burner D is used to heat the expander. in this instance instead of the neat-regulator A diaphragm-regulator B is shown shown in Fig. l, the one being the equivalent of the other. A pipe A leads from the reservoir A to a series of branch pipes a', having any of the ordinary forms of burners attached.

In Fig. 3 I have shown one form of diaphragm-regulator that I may use. t' is the diaphragm carrying a valve t, similarly located to the valve d, Fig. l, the liquid-inlet pipe being designated by the letter 2 and the outlet from the pressure-chamber by t3, while a spring k is shown encircling the diaphragmrod, and the pressure of this spring may be regulated by adjusting the screw-threaded cap 7c', which in the present instance is adaptedto the casing of the regulator.

It will be understood that when the device is used in connection with a heating-furnace the arrangement ot parts will be modified; butin all cases the regulator must be situated between the supply-reservoir andthe expander and the expander must connect with the upper portion of the reservoir.

In a separate application,Serial No. IGI-,550, I have claimed, broadly, the means for securing and maintaining constant pressure in the reservoir, the present application being confined to the special combination of the reservoir, the burner, and the expander with the regulator.

I claim as my inventionl. The combination of a reservoir, a burner, a passage leading from the reservoir to the burner, a regulator connected to said passage and controlling the flow of liquid therethrough, an expander within the heat zone of a burner connected to the passage between the regulator and the burner, and connected to the upper portion of the reservoir, substantially as described.

2. The combination ofa reservoir, a burner, a passage leading from the reservoir to the burner, a regulator connected to said passage, the valve of the regulator controlling the How of liquid through the passage, an expander within the heat Zone of the burner, connected to the passage between the valve of the regulator and the burner, and connected to the upper portion of the reservoir, substantially as described.

3. The combination with alamp,ofa burner, a reservoir, a tube extending from the reservoir to the burner, and within the heat Zone of the burner, a regulator for regulating the passage of fluid through the tube, a pipe extending from the discharge side of the regulator and coupled to the upper portion of the reservoir, and extending within the heat zone of the burner, whereby a given pressure will be maintained in the reservoir, substantially as described.

4. The combination in a burner, of a reservoir, a conduit leading from the reservoir to the burner, and two Valves in said conduit, that portion of the conduit which is between the valves being susceptible of being heated to gasify the liquid and start the burner, and said intervening portion of said conduit having a pipe connection with the reservoir, a portion of which connection is within the heat zone of t-he burner, whereby initial pressure is exerted upon the liquid in the reservoir, substantially as described.

5. The combination of a reservoir containing liquid hydrocarbons or other gasiliable fluids, a burner, a pipe leading from the reservoir to the burner, a regulator controlling the flow of Huid to the pipe, a valve in the burner and a valve in the pipe, a pipe coupled to the first-mentioned pipe between the two valves, and extending within the heat zone of the burner and connected to the upper portion of the reservoir and having a valve between its connection with the pipe and the point where it is in the heat Zone of the burner, substantially as and for the purpose set forth.

In vtestimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
